About Gravity Forms Email Blacklist
The Email Blacklist Add-on for Gravity Forms helps block submissions from users with generic or competitor email addresses. It allows site admins to create a list of domains that, if used in an email field on a Gravity Form, will cause a validation error and block the submission. These settings can be applied globally or on an individual email field basis.Screenshots
